Synthesia

Overview

Synthesia turns scripts into polished videos narrated by lifelike AI avatar presenters in 140+ languages. It is widely used for corporate training, how-tos, and localized explainer content without cameras or voice talent, and supports custom avatar cloning, an API, and SCORM export for LMS platforms. A free plan now lets you make short watermarked videos.

How Synthesia works

Synthesia replaces the camera. You write a script, choose an AI presenter and the platform generates a video of the avatar speaking it in the language you pick, with slides, screen recordings and branding around it.

Because translation and voice generation are built in, one script can become many localised videos. SCORM export and an API help teams slot videos into training systems and automated pipelines.

Getting started with Synthesia

1. Open the free plan and pick a presenter.
2. Paste your script and choose the language.
3. Add slides, screenshots or brand elements.
4. Generate, review and export, or push to your LMS.

Is Synthesia the right choice?

Synthesia suits training and internal communications at scale. If you only need audio, a pure voice platform costs less.

Who should use Synthesia

L&D and comms teams producing training and explainer videos at scale, especially where localization into many languages matters.
